Gather Prerequisites

Your build will fail if you are missing one of them, and the list changes. There are some options, however the make system can often find optional packages even if you do not intend to use them, so you may need to pass disable options.

Compile and Linking errors are frequent sources of discouragement. make careful note of the first occurrence of an error in your build process. It could be as simple as a bad environment variable, an unexpected version of a library or missing prerequisite.

Contribution
